Abstract Hydrogel electrolytes have been widely explored in aqueous zinc‐iodine batteries (AZIBs), light of their intrinsic strong water‐retention capability and superior flexibility hydrogel network. However, hydrogel‐based AZIBs are still facing challenges due to the inferior ionic conductivity, dendrite formation, corresponding fatigue‐induced damage. Herein, a electrolyte is designed engineered with preferentially aligned porous structures, where Zn 2+ can promptly transport along pores....
The spatial confinement effect in laser-induced plasma with different distances between the target surface and focal point is investigated by optical emission spectroscopy.
To effectively improve the far-field scanning range of an optical phased array (OPA), we propose a genetic algorithm using double fitness functions to optimize element arrangement one-dimensional non-uniform OPA and simulate with different numbers. The results show that more elements exhibits improved grating lobe suppression effect, optimized antenna pattern comprehensive performance upon employing function beam steering. Considering 128 as example, sidemode ratio (SMSR) 2.8-dB improvement...
Ultrafast thermionic emission from gold film irradiated with a femtosecond laser pulse in the presence of an additional electric field is analyzed using two-temperature equation combined modified Richardson equation. The calculated results show that duration below 1 ps. Supplying found to change metal surface. Given same fluence, this reduces work function metal, and thus improves efficiency emission. These help understand mechanism suggest ways improve emissions context ultrafast...
